Abstract :
In the present paper, an experimental study of the conduction phenomena in the composite insulator material mica-epoxy-novolac is presented, with an effort to suggest the possible conduction mechanisms. The study comprises the analyses of the influence of the temperature and frequencies of the electric field on the conductivity. The statistical analysis is performed of the results obtained the algorithm used for fitting the experimental data was Rosenbrock quasi-Newton
